Jennifer Lawrence Feeling Better Thanks to a 'Lot of Medication'

The ailing Silver Linings Playbook starlet is finally feeling fine after a reported bout with pneumonia.

"I'm so much better," Lawrence, 22, told reporters backstage at Sunday's Screen Actors Guild Awards, where she won for lead female actor. "I'm a lot better. I've been on a lot of medication and got a really cool inhaler, so I'm doing much better."

The actress – who was "laying low all week," a source told PEOPLE – missed Saturday's Australian Academy of Cinema and Television Arts International Awards due to the illness, according to her costar Jacki Weaver.

"Poor Jen is really sick," Weaver reportedly said, after accepting an award for Lawrence. "She really is sick. She has pneumonia."
